We delve into the escapist joys of a great summer read. David Remnick talks with Lee Child, whose thrillers about Jack Reacher—twenty-three books and counting, with a hundred million copies in print—bring the mystique of the cowboy to modern America. Amanda Petrusich says that the start of “Moby-Dick” nails the desperation to get out of town that afflicts every New Yorker; Vinson Cunningham explains how the usually tragic plays of Eugene O’Neill help him loosen up and find his rhythm as a prose writer; and Helen Rosner pulls out a cookbook to make a strawberry fool—a luridly hued but beautiful dessert that perfectly captures the taste of summer.
